version, hostinfo: recognize gokrazy as a distro
Now:
/tmp/breakglass3929186798 # /user/tailscale debug hostinfo
{
"IPNVersion": "1.23.0-date.20220107",
"OS": "linux",
"OSVersion": "Gokrazy; kernel=5.16.11",
"DeviceModel": "Raspberry Pi 4 Model B Rev 1.2",
"Hostname": "gokrazy",
"GoArch": "arm64"
}
Also, cache the distro lookup. It doesn't change while the program is
running:
name old time/op new time/op delta
Get-6 5.21µs ± 5% 0.00µs ± 3% -99.91% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
Get-6 792B ± 0% 0B -100.00% (p=0.008 n=5+5)
